Question 1

What should an interior design contract include?

Accepted Answer

A comprehensive interior design contract should cover the designer's scope of services (concept development, space planning, material selection, furniture procurement, project management, site visits), the project phases and deliverables for each phase (mood boards, floor plans, 3D renderings, material schedules, construction documents), the design fee structure (flat fee, hourly rate, percentage of project cost, or hybrid), procurement markup on furniture, fixtures, and materials (typically 20-35% above wholesale/trade pricing), the number of design revisions included in the base fee and the cost of additional revisions, the project timeline with milestone dates, intellectual property ownership of designs and specifications, the client approval process (written sign-off at each phase before the next begins), payment schedule tied to project milestones, cancellation and termination terms, and the designer's professional liability insurance.

Question 2

How is an interior design contract typically priced?

Accepted Answer

Interior designers use several pricing models, often in combination. Flat fee charges a single predetermined amount for the entire project or per phase — this is transparent and predictable for the client. Hourly rate charges the designer's time at an agreed rate (typically $100-$500/hour depending on the market and designer's experience), with hours tracked and invoiced periodically. Percentage of project cost calculates the fee as a percentage of the total construction and furnishing budget (typically 15-25%) — common for large residential and commercial projects. Procurement markup (also called cost-plus) charges the client the designer's trade/wholesale price for furniture and materials plus a markup of 20-35%. Most designers use a combination: a flat or hourly fee for design services plus a procurement markup on furnishings and materials purchased through the designer's trade accounts.

Question 3

Who owns the design work — the designer or the client?

Accepted Answer

This is one of the most important clauses in an interior design contract and the source of significant misunderstanding. By default under U.S. copyright law, the designer owns the copyright to their original design work — drawings, renderings, specifications, and material selections are creative works subject to copyright protection. The client receives an implied license to use the designs for the specific project, but does not own the designs themselves unless the contract includes an express assignment of intellectual property rights. Most interior design contracts grant the client a license to use the designs for the contracted project only, retain the designer's right to reproduce the designs in their portfolio and marketing materials, and restrict the client from sharing the designs with other designers or using them for additional projects without permission. If the client wants full ownership, the contract must include an explicit IP assignment clause.

Question 4

What is a procurement markup and is it negotiable?

Accepted Answer

A procurement markup is the percentage the designer adds above their trade (wholesale) price when purchasing furniture, fixtures, equipment, fabrics, wallcoverings, and other materials on behalf of the client. The standard markup ranges from 20-35%, though some designers charge as little as 15% and others as much as 50%. The markup compensates the designer for their expertise in selecting products, managing vendor relationships, placing and tracking orders, receiving and inspecting deliveries, coordinating delivery logistics, and handling returns and warranty claims. Some clients attempt to negotiate a lower markup in exchange for a higher design fee, which shifts the designer's compensation model. The contract should clearly state the markup percentage, whether it applies to all purchases or only to items procured through the designer's trade accounts, and whether the client may purchase items directly from retail sources (which bypasses the markup but also bypasses the designer's vendor management).

Question 5

How many design revisions are included in an interior design contract?

Accepted Answer

The revision clause is critical for managing both the client's expectations and the designer's time. Most contracts include a specified number of revisions per design phase — typically two to three rounds of revisions for concept presentations and two rounds for detailed specifications. Revisions beyond the included number are billed at the designer's hourly rate or at a pre-agreed per-revision fee. The contract should clearly define what constitutes a 'revision' versus a 'new direction' — adjusting the color of a sofa fabric is a revision; discarding the entire living room concept and starting over is a new direction that may trigger additional design fees. The contract should also specify the timeframe within which the client must provide revision feedback (typically 5-10 business days) to keep the project on schedule.

Question 6

What happens if the client cancels an interior design project?

Accepted Answer

The cancellation clause should distinguish between cancellation at different project stages because the designer's investment of time and creative effort increases as the project progresses. A typical cancellation structure includes: cancellation during the concept phase forfeits any non-refundable retainer (usually equivalent to the first milestone payment); cancellation during the design-development phase requires payment for all completed work plus any non-cancellable orders placed with vendors; cancellation during the procurement phase requires payment for all design work completed plus the cost of all orders placed (many trade-account orders cannot be cancelled or returned). The designer should retain the right to use all completed designs in their portfolio. Furniture and materials already ordered but not yet delivered present a special challenge — the contract should specify whether these orders transfer to the client or whether the designer can attempt to cancel them.

Question 7

Does an interior designer need a license?

Accepted Answer

Licensing requirements for interior designers vary dramatically by state. Approximately 28 states and jurisdictions have some form of interior design regulation — ranging from full practice licensure (which restricts who can call themselves an interior designer and perform certain design work) to title-only protection (which restricts who can use the title 'interior designer' but does not restrict practice). States like Florida, Louisiana, Nevada, and the District of Columbia require licensure or registration. States like California and New York do not require licensure for interior designers, though voluntary certification through NCIDQ (National Council for Interior Design Qualification) demonstrates professional competency. The contract should document the designer's credentials, license number (where applicable), and any relevant certifications (NCIDQ, ASID, IIDA membership).

Question 8

How should client approvals work in an interior design contract?

Accepted Answer

The client-approval process is the mechanism that prevents the most common interior design dispute: the client claims the final result is not what they envisioned. The contract should require written client approval (signed sign-off sheets or email confirmation) at each major project milestone: concept presentation, schematic design, design development, procurement specifications, and final selections. Once the client approves a phase, changes to that phase's deliverables trigger additional fees at the designer's hourly rate or per the revision policy. The contract should specify that the designer will not proceed to the next phase until written approval of the current phase is received, the approval turnaround time (typically 5-10 business days), and that silence or non-response past the turnaround period constitutes approval (to prevent project delays from unresponsive clients).
